Mirrors the Rocky workflow's two-part size reduction (27249770e "Reduce Rocky package size") on macOS: 1. Pass `--shared` to nix/build-all.py. The default builds IfcOpenShell as static libs, which means every plug-in dylib (schemas × 8, kernels × 3, mappings × 8, writers × 8, document serializers × ~4, linework processing) statically embeds a full copy of libIfcParse + libIfcGeom. With --shared the plug-ins reference @rpath/libIfcParse.dylib + @rpath/libIfcGeom.dylib and the per-plug-in dylib drops from ~30-50 MB to a few MB each. Dominant size win. 2. Filter `ifcopenshell.geometry.writer.*.dylib` out of BonsaiViewer's plug-in staging step in src/bonsaiviewer/CMakeLists.txt. These are the per-schema OBJ / glTF / DAE / STP / IGS / SVG / TTL export converters — heavy because each one inlines the full schema, and BonsaiViewer is a viewer, never an exporter, so they're pure deadweight inside the bundle. Additive on top of --shared. Bundle went 300 MB → expected ~100 MB, in line with Linux (~100 MB) and Windows (~80 MB). The IFCOPENSHELL_BUILD_PYTHON_WRAPPER=off gate is unchanged for now — once we confirm BonsaiViewer.app size + functionality look sane, we can ungate the Python wrapper and see if shared-builds-on-macOS shake out its install issues too.
